Alleged murderer Anna Adams, 38, today began crying wildly and denied stabbing the father of her youngest child to death at her arraignment in Queens Supreme Court — screaming, “I didn’t kill him!” — as a prosecutor read from her earlier written and oral statements to cops in which she said, “I killed him, I killed him, I killed him!”

“No! I didn’t say that, your Honor,” cried Adams as she hysterically interrupted Assistant District Attorney Patrick O’Conner while he was reading the second-degree murder charges against her from an indictment.

Adams had initially tried to pin the murder of boyfriend Jeffrey Perkins on her brother. But detectives later found a note that she had written and thrown in the trash inside her Jamaica home in which she allegedly confessed to grabbing a kitchen knife and fatally stabbed her boyfriend in the stomach and neck Sept. 6.

“I dragged him into the basement by myself and put the kids in the car and tried to clean up,” she allegedly wrote.

In other statements to police, she made the “I killed him!” comments, adding, “We argue all the time, but he didn’t deserve to die like that,” O’Conner said, reading from court documents.

Adams’s lawyer, Kathleen Gallo, asked the judge to set a low bail for her client so that Adams could to be with her two kids, ages 12 and 3, who have been in foster care since her arrest.

Justice Kenneth Holder refused, ordering Adams to remain in custody.

Adams has a previous conviction for reckless endangerment and four pending cases in Queens County for allegedly harassing her ex-boyfriend’s current girlfriend.
